gauges?
I got a pair of autometer gauges for christmas, one transmision temp, and the other is air/fuel ratio. The transmission temp gauge is short sweep electric. I am wandering what short sweep means? Also, I have a K&N high performance air charger which replaced the stock air intake, so the oxygen sensor is to the side of this, not inside like when stock. Does this make a difference? Has anybody installed these types of gauges, I am quite worried that it will be a difficult job, especially the tranny temp. Please help, any feedback much appriciated!
Thanks, Shane

The air fuel ratio meter uses a wire spliced into the oxygen sensor ouput. The oxygen sensor is screwed into a bung on the exhaust pipe.
On my 88 with a 300 six the heated oxygen sensor has three wires.
Two for the heater (12 volts and ground) and the output from the sensor that goes to the computer.

I just noticed your profile. Not sure on a 96 with a V8 and OBDII. You have at least one sensor in front of the catalytic converter and one behind it. (You may have 4 sensors).
You want to tap it to a front sensor.
The oxygen sensor has a short wire harness built into it. It then plugs into another wiring harness.
No need to unscrew it from the exhaust to wire your gauge.
If you install a new exhaust you may want to purchase a new o2 sensor.
The old one can be hard to remove.
You can install the air fuel gauge anytime. You just splice and solder a wire into the output wire of the oxygen sensor. Run the new wire to the input of your air fuel gauge. No need to remove the oxygen sensor.
Should have a diagram with the gauge.
One wire connects to a switch 12 volts so you only have power when the ignition is in run (or start if you want).
One wire for ground.
One or two wires for the backlighting bulb. (if you have two wires tie one to ground).
One wire input from the oxygen sensor.

Thanks for the info, it sounds like a bit of a job. How long would this take? I wander if it would be easier to just bring it to a shop to do it, but could be too pricey if it takes a little while, if so probably try myself???
